CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 626,552, dated June 6,1899. Application filed December 27, 1898. Serial No- 700,455. (Nomodel.)

To all whom may concern.-

Be it known that I, GEORGE O. MURRAY, of the city of St. Louis, State ofMissouri, have invented certain new and useful Improvements inCar-Trucks, of which the'following is a full,-clear, and exactdescription, reference being had to the accompanying drawings, forming apart thereof.

My invention relates to car-trucks; and it consists of the novelconstruction, combination, and arrangement of parts hereinafterdescribed and claimed.

Figure 1 is a side elevation of myimproved car truck. Fig. 2 is a planview thereof. Fig. 3 is a view in perspective of one of the side framesof my improved car-truck. Fig. 4 is a view in perspective of the matingplates which form the housing for the upper end of one of the springs ofthe truck. Fig. 5 is a view in perspective of a pair of matingjournal-box guides. Fig. 6 is a view in perspective of one of thewearing-plates made use of in carrying out myinvention. Fig. 7 isahorizontal sectional view taken approximately on the line 7 7 of Fig.3. Fig.8 is a horizontal sectional view taken approximately on the line8 S of Fig. 3 and looking upwardly. Fig. 9 is a View in perspective of abearing-plate such as is located in the spring-housings.

In the construction of my improved cartruck I make use of a bolster ortransom 1, which is preferably constructed of a pair of I-beams, to theends of which are riveted or bolted the side frames of the truck. Eachofthese side frames comprises an I-beam 2, the center of which isdepressed, together with the lower member 3, which is preferably a T-barhaving its center arched, or said lower member may be an I-beam. Asheretofore stated, the ends of the bolster 1 are secured to. the sideframes by rivets or bolts, and to further strengthen the frame of thetruck so constructed clips at are riveted to the top of the T-bar 3 andto the flanges at the ends of the I-beams forming the transom or bolster1.

Located upon top of the ends of the bolster or transom are the plates 5,on which the side bearings of the truck operate, and located at thecenter of the bolster or transom is a kingpin guide or seat 6, the samebeing securely riveted or bolted to the webs of the I-beams forming thebolster or transom.

Formed in the flanges of the T-bar 3, adjacent its ends, are the pairsof rectangular notches 7, and formed in the lower flanges of the I-beam2, in alinement with said pairs of notches 7, are the pairs of notches8, all of these notches extending approximately halfway through thewidth of the flange, and the balance of the flanges between the pairs ofnotches Sin the I-beam 2 is removed, the purpose of which will bepresently set forth. Seated upon the ends of the I-beams 2, one on eachside thereof, are the plates 9, the same being of the same size andconstruction and equal in width to the web of said I-beam, with theouter faces of which plates are formed integral the semicircular casings10, there being the vertically-arranged flanges 11 formed integral withthe outer faces of the ends of said plates. When these plates arecorrectly positioned upon the web of the I-beam, the ends of the casings1O coincide with the inner ends of the pair of notches 8, thus formingthe circular housings for the upper ends of the springs.

The journal-box guides, (seen in Fig. 5,) a pair of which have theirupper ends seated upon each end of the plates 9,comprise the verticalplates 12, in the upper ends of which plates are formed theoppositely-arranged notches 13,Which pass into the pairs of notches 8 inthe lower flange of the I-beam 2, which notches also engage upon theportions of the which extend between the material of said plates 12surrounding the notches 13 and 14. The lower ends of the pair ofplatesl2 that is located adjacent the outer ends of the side frame areextended inwardly toward the center of said frame, while the lower endsof the ICC inner pair of plates 12 are extended outwardly to meet theextended inner ends of the outer pair of plates. The ends of the innerpair of vertical plates 12 are held together and to the inner ends ofthe plates'9 andto the webs of the I-beam 2 and T-bar 3 by the rivets16, said plates 9 being held to the web of the I-beam 2 by the rivets17. The outer pair of plates v12 are held to the ends of the plates 9and to the web of theT -bar 3 bythe bolts 18, the nuts for said boltsbeing upon the inside faces of the-side frames.

Located within the spring-housings, composed of the mating casings 10,is a disk 19, the same being provided'on its under side with'a lug 20,said disk being held within said housing by the rivets 21, which passthrough the top of the casings 10.

The journal-boxes 22 used in connection with my improved truck are ofthe ordinary construction and provided in their'sides with thevertically-arranged groove 23, and formed integral with the top of eachbox is a circular lug 24, the usual helical coil-springs 25 beinginterposed between the journal-box and the plate 19 in the top of thespring-housing, the ends of said spring being seated upon the circularlugs 20 and 24.

The wearing-plates 26 engage in the vertical groove 23, formed in thesides of the journal-boxes, said wearing-plates being provided withintegral rearwardly-projecting ribs 2'7, which are located between thepairs of journal-box guides.

By my improved construction a very strong, simple, and compact car-truckis produced, and whenever desired the bolts 18 at either or both ends ofthe truck may be quickly removed in order to take out the axle, wheels,and journal-boxes.

By making use of I-beams and T- bars for the side frames theconstruction of the truck is greatly simplified and cheapened, inasmuchas no large castings or specially-formed parts are required, and theentire truck may be as sembled in any ordinary car-repair shop.

I claim 1. In a car-truck, a bolster, a pair of I- beams havingdepressed centers and a pair of T-bars having arched centers, a pair ofwhich I-beams and T-bars are rigidly secured to the ends of the bolsterand to each other, substantially as specified.
